ER308LSI
Alloy Type: A5.9, STAINLESS STEEL Bare, Cored and Stranded Electrodes
ER308LSI has the same analysis as ER308L but with a higher silicon content. The higher silicon content improves arc stability, bead appearance and wetting action. ER308LSI produces exceptionally smooth welds for applications that require a good cosmetic appearance. This product is used primarily with welding grades 304 and 308.
